The relationship between decoration materials and home health

In recent years, indoor environmental protection has become a common concern of all sectors of society. Liu Xiaoyi, vice president and secretary-general of the China Building Decoration Association, said that with the rapid development of the construction industry, the problem of indoor air pollution caused by building decoration materials and household materials has become increasingly serious, which has caused certain harm to people's health. Tian Dexiang, a professor at the Peking University Environmental Science Center, also pointed out that at present, the pollution situation of China's indoor environment is particularly attractive, and the situation of formaldehyde and xylene exceeding the standard is rather severe.

Li Guocun believes that indoor air pollution such as formaldehyde is mainly concentrated in the area about 1 meter above the surface, which is the sleep breathing zone of people. He also said that under the floor is the largest, most concealed, and most important and most difficult indoor environmental pollution source in the family. It is a mixture of bacteria, mites, pathogens and other toxic and harmful substances that endanger human health. Zhang Liubo, director of the disinfection branch of the Chinese Preventive Medicine Association, also pointed out that these toxic and harmful substances are very harmful to the health of family members, and many diseases are related to it.

In fact, indoor air quality issues have attracted the attention of the state. In the “Twelfth Five-Year Plan” issued by the state in 2011, it was clearly stated that the requirements for green building, green construction and green materials should be promoted. According to the reporter's inspection, the state has issued two indoor air quality inspection standards for "Household Environmental Pollution Control Code for Civil Buildings" and "Indoor Air Quality Standards". Among them, the Indoor Air Quality Standard is the recommended standard for indoor indoor air quality testing, which imposes explicit limits on physical, chemical, biological and radioactive indicators in indoor air.

Despite this, China's indoor air quality is still not optimistic. Not long ago, the results of the indoor environmental safety survey conducted by 22 urban consumer rights alliances in 100 new urban residences across the country showed that the pollution situation of China's indoor environment is not optimistic. More than 4% of newly renovated houses have exceeded the standard of pollution, and the rate of self-refurbishment of new houses is only 22%. From the analysis of non-standard data, mainly formaldehyde and TVOC (total volatile organic compounds) two harmful substances exceeded the standard, of which formaldehyde exceeded the standard of 56.1%; the TVOC exceeded the standard of 70.7%; formaldehyde and TVOC Both exceeded the standard by 41.5%.

Due to various factors such as construction decoration materials and poor quality construction control, the indoor fresh air is insufficient, and the health problems caused by the increase of indoor air pollution are also rising. The release of harmful substances such as formaldehyde, volatile organic compounds and benzene from interior decoration materials and household products has seriously threatened people's health and life, and the resulting cases of poisoning deaths have occurred from time to time.

The healthy environment of the home is closely related to our physical health. We must ensure a healthy body condition, effective prevention and control of home improvement pollution, and less need to pay attention to building materials selection, decoration construction and post-maintenance.

First, carefully select materials to select environmentally safe building materials

The building materials used in home decoration are the main source of decoration pollution. The harmful substances of building materials exceed the standard. After the decoration is completed, the pollutants will continue to be released, which poses a great threat to human health and safety. Therefore, it is necessary to choose non-toxic and harmless when choosing building materials. Or low-toxic, low-emission building materials.

Hazardous substances contained in building materials: A variety of chemical substances harmful to the human body contained in inferior building materials, such as formaldehyde, benzene contained in laminate flooring, paint, radioactive materials in stone, carcinogens contained in cement and stone powder. The National Code for Indoor Environmental Pollution Control for Civil Buildings, promulgated and implemented this year, lists five major pollutants: formaldehyde, benzene, ammonia, volatile organic compounds, and radioactive cesium. When selecting building materials, it is necessary to pay attention to whether these pollutants exceed the standard.

Environmentally-friendly building materials: The concept of environmentally-friendly building materials is also very popular in recent years. So what kind of building materials can be regarded as environmentally-friendly and safe building materials? As the pioneer of environmentally-friendly household accessories brand, GSD has been advocating “building is a humanistic concern” since its establishment. The concept is to build a high-comfort, high-environment living space with low energy consumption as the vision, to solve the impact of industrial civilization on the living environment of the home, and to deeply study the various aspects of home space waterproofing, bonding, caulking, space care, etc. The topic, while using high-tech means, the negative ions, seaweed mud polyoxyl molecules into the materials needed for home decoration, creating more green factors for human home.

Second, pay attention to reduce pollution during construction and decoration

There are many sources of indoor environmental pollution, and a considerable part of them are caused by improper materials used in the decoration process, including volatile organic compounds such as formaldehyde, benzene and xylene. Therefore, materials with less organic pollutant content should be selected in the decoration process.

Consumers and home improvement companies should also rationally design according to the area of ​​the house, choose a non-polluting construction process, create a good indoor ventilation environment, and at the same time, the density of the indoor furniture, the space carrying capacity of the house, and the indoor air after the completion of the decoration. Problems such as purification and testing are also issues that must be paid attention to during renovation.

New houses should be green and green. That is, in the decoration, try to use natural materials, or decorative materials that are proved to be harmless to the human body, especially the formaldehyde content in the laminate flooring, the radioactivity of the stone, and the xylene content of the coating.

After the renovation of the new house is completed, it must be ventilated every day. After at least 2 months, it is determined that there is no smell to stay. If you stay indoors for a long time every day, you should always open the window to ventilate and at the same time, pay attention to doing some outdoor activities. If the new house is tested, the formaldehyde content, radioactivity and other indicators exceed the standard. The best way at present is to pay attention to the ventilation of the room window.

Third, the pollution control to remove harmful substances after renovation

After the decoration is completed, ventilation and ventilation are important means to remove toxic and harmful substances in the room. In addition, there are some ways to speed up the cleaning of pollution and minimize the amount of household pollutants.

In the tradition, people often use some folk odor removal methods: use orange peel, lemon peel, etc. to absorb indoor harmful gases, or by placing some plants to remove household odor. In the market, it is common to use Tianna water and turpent water for the removal of paint odor, and air fresheners are also used for the removal of odor. However, these products are synthetic compounds, which are only simple coverage of odors, and have little effect and even cause secondary pollution.

Suggestions from GSD Cluster:

Chemical treatment: Air pollution control products refined from natural herbal extracts. The Ningda Oxygen Home Series is a new generation of home health air spray consisting of three products, namely formaldehyde scavenger, paint deodorant and household odor scavenger. It is specially designed for the removal of different organic volatile odors, environmentally safe, strong adsorption, and will not cause secondary pollution.

Physical management: adsorption of polluting gases using materials such as activated carbon, silica gel and molecular sieves, especially the use of activated carbon products for filtration adsorption, ie physical adsorption. Or a negative ion purification device is used, and negative ions are attached to the contaminated gas molecules to form large ions and settle down. The newly-launched activated carbon purification package and negative ion air freshening package adopts Hainan natural pure coconut shell activated carbon, which has stronger adsorption capacity for absorbing formaldehyde, benzene and TVOC, and helps to keep the indoor air fresh and comfortable and remove indoor environmental pollution.

Pay attention to keep the room ventilated and carry out air treatment regularly.
